The Department of Transportation (DOT) requires a medical examination for all drivers to receive and maintain a CDL (commercial driver’s license). Part of that assessment is a determination of whether the driver has, or requires testing for, sleep apnea (a.k.a. “obstructive sleep apnea” or “OSA”).  If the driver is diagnosed with OSA they must show compliance with use of a CPAP (continuous positive airway pressure) machine. This information must be presented to a certified medical examiner at the time of initial exam or recertification. Typically, a report can be downloaded from the CPAP device or app. This must show use of the CPAP machine at least four (4) hours per night AND at least 70 percent of the time before the driver can be certified; non-compliance is not an option.  Drivers should plan ahead, especially for recertification, and bring the report to the examination to avoid any delays.  Call us to schedule your DOT exam or with any questions about OSA/CPAP requirements.
